This invention relatesto a spare wheel and;

tire lock; 7

An object of the invention isto provide a lock which assures fullprotection against the theft of either or both thespare-wheel of anautomobile and'th-e tire-carried thereby.

Another object is toprovi'de a spare wheel and tire lock so constructedthat the parts thereofwill not rattleduring operationof the automobile.

Another-object is to provide a spare wheel and tire lock which is strongand-iseasily operated and-v applied.

Another object is to provide a spare wheel and tire lock which iscompact, yet possesses great strengths ,Another object is to provide aspare wheel and the lock which issmall and of a-pl'easing designimproving the appearance of the spare 'wheel'rrather than: detractingthere-V from.

Other objects and-advantages will become apparent as the descriptionproceeds.

the wheel hub and spare tire carrier being The sparewheel and tirelock'of the present invention is shown as used upon acer- .tain' type ofdemountable Wire or steel spokewheel' but, it should be'understood, thatsuch showing is for purposes of illustration only and that it isadaptable for-use upon other types of Wheels. Also, a preferredform-oflock per se has been illustrated, and while this form ispreferable and novel, it is --with-- in the contemplation of the-presentin-vention that other forms of locks might be usedin combinationwith the other elements.

' In Figure l aporti-onof the wheel is broken-'away'so as'to-show aspare wheel car- I rier 10 adapted to be connected to apart of amotorvehicle by a connecting stem or -portion 11, or in any" other well knownmanner;

wheel to which it is attached,'and is pro-- vided with a number ofoutwardlyprojecting studs 12' suitably fixedly secured at their in pThis spare wheel carrier is preferably circu; 7 law in shape, conformingto' the part of the:

nor ends and provided with threads upon 7 their outwardly extendingends, as is well; known in the art. 4 The number of these studs andthe'arrangementin-which they are spaced about the carrier Will vary in;accordancewith the Wheel which is tobe mounted thereon and will,ofcourse, be 'governed -by the,v

number of openings in the wheel hub. :As the wheel shown herein'isoir'x-thedemounb able type, the manner inwhich it wouldlb'emounted-uponthe active-hubs; and upon: the I spare wheel carrier issubstantially the same and'is well understood in the art; However, abrief descriptionof the-wheel and its mode of attachment tothe. carrierwill, perhaps, enable the present invention to be better understood'.

The wheel shown comprises a hub 13.formeell with an annular bead: 14adjacent its :outer. end andan annular flanged hub 'plate15- at itsinner (3nd,, It is this last named portion which is adapted to fit overthe active hubs of the vehicle and over theispare wheel carrier and tohave anumberof openings in its: face through which project the studbolts of the hubs or of thecarrierwhich, in the present: instance, arefive in number. Wire or steelspokes' 16;, connected: toqthefflanged.

in position by cap nuts 18 screwed onto the threaded portions of thestuds and provided with enlarged conically tapered portions 18a fittinginto the openings and upon which the plate bears. Of'course, the samemode of connection is used when the wheel is applied to the active hubsof the vehiolef The cap nuts 18 are of well-known construction with theexception of the one with which the lock isto be used. This nuthas anoutwardly extended reduced portion 19, the opposite faces of which-arefiat and are connected by a transversely extending-:opening 20arrangedapproximately at the middle of the portion 19. Since the portion19 is.

reduced in thickness, shoulders 21 are provided on each side ofitsjunction point with the main body of the nut.' This special form of nutis preferably applied to the stud which lies below the hub 13 and isin'vertical alignment therewith, although, of course, it could be usedupon any of the other studs.

connection with the special form of cap nut comprisestwo relativelyrotatable parts 22 v and 23, the part 22 beingsubstantially cylindricaland the part23 substantially disc shaped. The part 22 is provided with acircular recess extending fromone end substantially to the other, theupper portion of which is enlarged to receive a reduced circularextension 24 from the underside of the part 23, while the lower part ofwhich .is

reduced to receive a series of nested tubular. tumblers 25 of differentlengths arranged; concentricallyto each other. The, reduced extension 24of the part 23 'of the lock is also provided with a circularrecessforthe reception of. a similar series of shorter tumblers 26 arrangedconcentrically to the tumblers in the part 22. Ordinarily, the tumlers25 in the part 22 extendupwardly past the end .of' the projection 24 of.the other partbecause of springs arranged in the "reduced recess withinwhich they are housed; When it is desired to open orunlock the looka keyis inserted through a-key opening 27 in the top of the part 23 and thetumblers 26 are selectively pushed downwardly, in turn uponthe two partsmay be relatively rd tatedr It is understood that the twosets of:tumblers while arranged concentric to each other are arranged eccentricto the axis of.

rotation of the parts 22 and 23 and that the part 23 is rotatably keyedby means of a key 28 against axial displacement from the part 22.

The tumbler arrangement of the lock just described employs theprinciples disclosed in my two prior Patents Nos. 1,390,222 dated- Eachof the parts 22 and 23 are provided a with integral shackle arms 29 and30 which,

when the lock is in locked position, have their inner flat faces 81 and32 in alignment but spaced apart sincethe arm 29 is carried adjacent theend of the part 22 furthest removed from the part 23. The face ,31 ofthe shackle arm 29 is provided with a pin 33 projectingperpendiculartherefrom and extending across the space between the two faces of theshackle arms when they are in locked position.

7 VJ hen it is desiredto apply the lock to the I cap nut, which has beenpreviously screwed upon the stud, the pin 33 is passedthrough theopening 20 in the extension 19 of the nut with the face 31 of theshackle arm 29- lhe lock which is preferablefor use in:

in close engagement with one of the flat faces of theextension 19 andsince the pin 33 is of a length approximating the thickness of theprojection 19 the part 2310f the lock when rotated in the desireddirection: will havethe face 32 of'theshackle arm 3:0 eIi-i gaging theother flat face of the projection 19 and the free end of the pin 33. Thelock; is thus securely fastened to the cap nut which cannot now berotated, since'the, lock is so proportioned that rotativemovement thereof will causeit to strike against a part 10f the wheel, preferably thehub 13.

' Theconstruetionthus far relatesto-the spare wheel lockingfeature ofthe invention,

while the part now to be described relates pri-.

marily to the tire loclrfeature thereof, although there-1s a'deci'dedco-operat1on.;between th s feature and thefornier one inthat there is amutual co-action of the parts to e f.:-

fectcertain combined results.

In the form shown, a loop-likemember34 of suitable material istadaptedto surround the tire and has converging upwardly extend ng portions 35and parallel legs 36. at

their upper ends, such last named portions 37- placed over;the caplnutand the lock ap; plied thereto, that not only will protection befurnished against theft ofthe spare wheel but also it will be virtuallyimpossible or at. least, extremely difficult for any one to: remove thetire from the spare wheel. Al

mama:

As already mentioned, the loop 8% may be constructed of any suitablematerial but it is contemplated to have the same formed of a materialthat has a natural spring tendency so that the loops 87 will beconstantly forced,

apart by the bowed portion and the legs 36 adjacent the lock will engagetherewith and will swing the same outwardly upon the pin 33 as a pivot,until the shackles 29 and 30 engage tightly against the flanges 21 ofthe cap nut. It will thus be seen that'the parts themselves because ofthis maintain each other against vibration and rattling during operationof the vehicle and also that theshoulder 21 forms an effective stopagainst the outward swinging of the lock in an at tempt to remove thesame from the cap nut.

In actual practice it has been'found that a heavy, hardened steel loopis suitable for the part encircling the tire and that such a loop wouldpossess the required inherent re-f siliency just mentioned. It shouldalso be noted that the loop may be enameled to correspond to the colorof the spokes and'that, therefore, it will blend into the generalappearance. of the wheel and not detract therefrom.

The spare wheel and tire lock disclosed in,

Figure 7 is of a slightly modified form. Instead of providing both ofthe legs 36 of the loop with the cap nut engaging loops 37 only theone-adjacent to the hub plate 15 is so provided, while the leg adjacentto the'lock is shorter than the other leg and is attached to the lock.Ineffecting this attachment of the leg to the lock, the part 22 of thelock is provided with a bore 38 adjacent its rear side and into whichthe upper end of the outer leg 86 extends. Although the leg 36 isnotched and shown in the drawing as extending into the bore and heldtherein by upsetting the lock into the notch, it should be understoodthat the leg might merely extend 'into a recess in the underside of thelock and be welded or otherwise secured therein.

It will be seen that in this modified form the lock and the loop or tireretaining member form a unit. In applying this form of the spare wheeland tire lock, the inner leg of the loop isspread apart from the outerleg and the loop passed around the tire, then the loop 37 at the upperend of the inner leg is passed over the cap nut as in the previouslydescribed form, after which the lock is locked in position on the capnut.

The inherent spring tendency in the loop will force the lock outwardlyuntil the shackle arms; engage. the shoulder 21 of vthe cap nut, whenthe parts will be held, against "rattling and 'thewlock held againstmovement outwardly of thew-heel f a; I
